What The Iran War Means For Global Trade

The Strait of Hormuz doesn’t need to stay closed for long to rattle the entire world economy. When that corridor tightens, we feel it fast in oil and LNG supply, fertilizer availability, freight capacity, and the everyday cost of living. I connect the dots between military action involving Iran, disrupted regional infrastructure, and the real-world supply chain delays that show up as higher prices at the pump, at the store, and inside factory cost sheets.

We also put numbers around something that’s usually left as a shrug: what modern war actually costs. Using clear cost categories, I walk through direct strike operations, high-value munitions, equipment losses, force protection, and the long tail of stockpile replenishment and industrial base strain. The estimate lands around $25 billion to $45 billion over roughly 91 days, and I explain why the burden is so hard to track across defense budgets and why that opacity matters for strategy and accountability.

From there, the business news roundup widens the lens: drone warfare and AI-enabled targeting, policy pressure points in the UK economy, a brewing constraint in Group III base oils affecting automakers, and the shift from low-cost networks to risk-adjusted supply chain design. We also cover how shipping liability is changing after the Francis Scott Key Bridge case, plus new data pointing to a world of frequent maritime disruptions, longer routings, and rising insurance and compliance costs.

Iran Conflict And Hormuz Shutdown

Tony Hines 0:11

Hello, Tony Hines here. Good to have you along. Well, we're quite a time into the war now, aren't we, in uh Iran? And I say war, it's the United States and its military action against Iran, along with Israel. And of course Iran has retaliated. It retaliated in quite a strange way, really. It's retaliated against all the oil infrastructure in the region and attacked its neighbors. So not quite sure how that will settle down when it's all over. But we keep getting told it's about to be over. There's a deal, as uh the US administration likes to say, a deal is on the way. But it's not quite finalized yet. There's still this hangover about uranium and uranium enrichment. And obviously the United States' aim is not for Iran to have nuclear weapons. But uh is that a bit like King Canute trying to turn the tide back? Who knows? Once the genie's at the bottle, it's difficult to put it back in. Meanwhile, of course, while it's all continuing, the Strait of Hormuz is still closed. Very few ships are passing. The few that do seem to get through are on the way to China and India, and it's LNG supplies, fertilizer and oil and gas that's having difficulty getting out. But of course there's lots of other products that come through that route as well, and those two are having a difficult time getting out of the Strait of Hormuz. The one thing that has to be resisted, of course, is tolls. It isn't sensible to have tolls on trade routes, and the International Maritime Organization doesn't want that either. Apart from all the death, destruction, there's disruption and delay to global supply chains, and that's having a great impact. And it's also having an impact on many countries around the world, not least the United States with its inflation, and consumers, probably about five hundred dollars per annum, worse off as a result of this military action. Fuel costs have risen, taxes will go up to pay for the war, LNG in short supply in many parts of the world, and fertilizers too, so it'll affect agriculture, it will affect deliveries, and of course, while the Straits of Hormuz is closed, none of this can improve. And manufacturing costs have increased. And while all these costs are going up, then the outlook is bleak for many.

Counting The Real Cost Of War

Tony Hines 3:05

US military action involving Iran has generated a complex and expensive set of operational, logistical, and strategic costs. While no single official figure exists for the cost of the war, a synthesis of defense budget data, historical analogues and munition cost modeling places the total expenditure in the range of 25 to 45 billion US dollars. This includes direct strike operations, high value munitions, equipment losses, force protection measures, and long-term stockpile replenishment. The financial burden is distributed across multiple budget lines, making it difficult for policymakers and the public to track. Understanding these costs is essential for evaluating the strategic value of continued engagement in the region. U.S. action in Iran is rooted in a decade of escalating tensions, proxy attacks, and threats to regional stability. Iran's network of militias in Iraq, Syria, Lebanon, and Yemen has repeatedly targeted US forces and commercial shipping. In response, the United States has conducted precision strikes, reinforced urban naval assets, and expanded defensive measures across the Gulf. The strategic objective is deterrence, preventing Iran from projecting power, protecting United States personnel, and ensuring the security of global energy flows. War cost accounting is notoriously opaque. Analysts typically rely on CRS methodology, CRS's Congressional Research Service, which divides costs into cost categories for the operation. They have direct operational costs, that's munitions, fuel, sorties, deployments, and that's typically about 30-40% of the cost. Equipment losses and damage for drones, aircraft and base infrastructure are about 20 to 30%. Force protection and posture, air defence batteries, hardened bases, 25 to 35%, and long-term replenishment for those missiles, building those missile stockpiles and maintenance cycles 10 to 20%. And that allows us here to build a realistic estimate, even without official totals. We're looking at munitions, tomahawk cruise missiles, about one and a half to two million dollars. JA SSM ER one point three to one point eight million dollars. They're stealth precision weapons. Patriot Pack 3, $4 to $5 million. There are defense interceptors. The SM6, $4.3 to $4.7 million. It's a multi-role missile. And those THAD interceptors, THAAAD, they're about $11 to $24 million each. And they're high altitude defense weapons. So each one of those weapons, that's the unit cost for those weapons. The estimated direct operational cost is somewhere between $8 and $15 billion for this 91 day military exercise. And equipment losses, those are estimated for the MQ9 Reaper, $30 million. Several were lost to hostile fire. The radar systems that went down, damaged in base attacks, $50 to $200 million. Aircraft shelters where reconstruction is required, about $5 to $15 million, and communication nodes where replacements were needed, $10 to $40 million. The total estimated cost for the equipment losses $6 to $12 billion. And then the added Patriot and THAD batteries, hardened shelters, naval reinforcements, and expanded ISR networks, which were required to protect the region. They're costing somewhere around ten to twenty billion dollars. The long-term budgetary implications are substantial. Missile procurement requires about 70 billion. Stockpile replenishment cycles are of three to seven years, and the industrial base strain is on companies like Raytheon, Lockheed, and Northrop. There's increased maintenance for the aircraft and ships. If we look at a comparison with the Iraq-Syria conflict, the munitions cost per strike is much higher. There's greater air defence requirements, there's broader regional footprint, more area being covered in this particular military exercise, and there's more sophisticated adversary capabilities. The financial burden raises strategic questions. Are the costs proportionate to the deterrence achieved? How sustainable is the current posture? What are the opportunity costs for Indo-Pacific and NATO priorities? And how can transparency be improved in defence accounting? So we're saying it's somewhere between 25 to 45 billion overall. In the 91 days this war has been going on. Other estimates range between $40 billion and $50 billion. So it could be higher, because it's very difficult to pinpoint all the cost.

Preview Of Mineral Wars Book

Tony Hines 9:13

And I've got a great program coming down a track, and I'm sure you'll enjoy it very much. It's with Tomasz Nadrowski, and he's gonna speak about his new book, Mineral Wars. And I kid you not, this is a really great book. And for me to say that is unusual, but it's full of detail, it's full of useful information about where the future's headed when it comes to these mineral wars and who has control of those supply chains. And it's a real eye opener, and Tomasz was excellent in giving some key pointers. So do stop by, have a listen, and I hope you enjoy the program.

Global Headlines Start Rolling

Tony Hines 10:02

Let's take a look now at all the other news in the headlines this week.

Lebanon Escalation And Evacuations

Tony Hines 10:07

Israel has stepped up its attacks against Hezbollah in southern Lebanon. It's extended the combat zone and its operations, and it's working in the area south of the Zarani River, which is about forty kilometers or twenty five miles north of the Israeli border. It's told all residents to evacuate.

Alberta Separatism And Energy Politics

Tony Hines 10:31

Now I've been reading for the past few weeks about Alberta wanting to leave Canada. It appears that this is all over the separatist group that want to see oil and gas resources prioritized. I don't think it would necessarily win any referendum, but it is a concern for the Canadian government, and you have to ask why would they want to join the United States for any other reason than to exploit those oil and gas resources because they know President Trump is partial to oil and gas. Of course I suspect that the US administration under Trump would be very keen to have Alberta. Prime Minister Carney warned separatists that Alberta would regret leaving a federation if they chose to do so, and he compared them to Brexiteers in Britain who voted to leave the EU. Alberta's Premier has called for a public ballot on october nineteenth.

Drone Warfare And AI Targeting

Tony Hines 11:38

There's so much smart tech in modern warfare, it's becoming very expensive in a different way than building those patriot missiles and so on. Western armies are well behind the curve in this one. They need far more jammers and counter drone defenses, and of course there's a training that goes with that. NATO's getting some help, of course, from Ukrainians who are pretty well up that curve when it comes to tackling drone warfare. They've been very successful in knocking out Russian drones. New technology has also employed AI enabled software allowing armies to find and strike targets, and this is happening on an unimaginable speed and scale, according to The Economist this week. One suspects that the current US administration has weakened the strength of the United States by criticizing its own allies, and that will make it very difficult to stave off future aggressors. Wars are never swift, and they're never a good option. They cost more than you think, as we've learnt in this episode, and that's in terms of lives lost. It's in terms of monetary cost, global trade, and the damage it does to relationships around the world. It takes years to repair the damage from warfare, especially modern warfare. So never believe those great leaders that say I can get this done in a day, because they just

Cuba Pressure And Carrier Posture

Tony Hines 13:17

won't. You may recall when America took over Venezuela and grabbed the dictator from Caracas back on january third, President Trump said Cuba was going down next. Most people were quite surprised by that. For about seven decades now Cuba's locked up its dissidents, and it impoverished the country. Ordinary Cubans are now finding it difficult to buy food and get medicine. Cuba's only a low level threat to America's security. So why would America want to take Cuba down? I suppose one irritant is that they have listening posts being so close to the coast of Florida, they're only about two hundred kilometers away from Florida. And both Russia and China have listening posts from Cuba. It would be better if they got the regime to the negotiating table. Marco Rubio and President Trump have said they want regime change. On may twentieth, the USS Nimitz, one of America's eleven nuclear powered aircraft carriers, arrived in the Caribbean. It was the same day that the American Department of Justice indicted Rao Castra, Cuba's de facto leader. They don't think they can reach a peaceful agreement, and Mr Trump has said he'll do what it takes. It sounds very similar to what happened in Venezuela. So if the United States hasn't got enough on its plate, this is another one. Maybe.

UK NEETs And Stagflation Risk

Tony Hines 14:52

In Britain this week there was concern about the number of youngsters, what they call NEETs, not employment, education, training, or in work, and the welfare bill and the damage that that can do to young people's mental health. And there's a new report out by Alan Milburn, which outlines all the issues. So what policies will come from that? And will it get young people back into education, training and work? Because that's got to be a big policy aim. Of course, governments have to offer incentives, but the Chancellor of the Exchequer in the past week has offered a very strange incentive to take VAT off visits to theme parks, and some people are saying that that's not enough. And I guess they'd probably be right, because there has to be a lot more solid policy to ensure that spending goes up and incomes are maintained in those leisure and hospitality industries that are suffering greatly from the policies of the current administration. Much damage, of course, has been done to the treasury plans in the United Kingdom by the Middle East war. But there is also a fundamental underlying problem about helping businesses to get through sticky patches, and we're in one very big sticky patch right now. There are going to be some hard choices to be made with regard to policy, and there are going to be some wrong choices made too. Because there isn't a clear plan on how to get things moving. As John Maynard Keynes said, money has to circulate round the economy. It's the only way in which incomes can rise, tax takes can rise. But if you hit a downward spiral where inflation rises, people don't spend, and taxes go down, and you get stagflation, that's a serious

Auto Supply Squeeze On Base Oils

Tony Hines 17:00

issue. There's been a tightening of group three based oils in the supply of them. They're critical for synthetic motor oils and transmission fluids, and it's now emerging as a major constraint for automakers. The Middle East conflict and the disrupted Gulf region refining threaten to leave supplies running dry by June, and rationing already underway at Nissan and warnings issued by Toyota. This could cascade interproduction delays, higher service costs, and renewed parts bottlenecks. So it won't just increase costs of course for manufacturers. This could have a price spike effect for those vehicles being manufactured in the marketplace.

Redesigning Energy Logistics For Risk

Tony Hines 17:45

The geopolitical instability around the Strait of Hormuz, where they handle 20% of global oil and LNG flows, is forcing companies and governments to redesign energy logistics around redundancy, alternative corridors, and storage capacity. The shift makes a move away from lower cost networks to risk adjusted supply chain design, elevating pipelines and deep water ports outside the Gulf as strategic assets. So is this the long term future beyond the current crisis? And one has to say it's a self-inflicted crisis. It wasn't something that needed to happen. But it's putting everybody's cost up, and we've already seen the average consumer in the United States will be five hundred dollars worse off because of those costs, and likely to rise further.

Ford Reworks EV Battery Strategy

Tony Hines 18:37

Ford has taken a nineteen point five billion write down and is restructuring its EV battery joint ventures, pivoting from single purpose EV lines to multi-energy flexible manufacturing platforms. Battery plants in Kentucky and Michigan are being repurposed for stationary energy storage and data center infrastructure, signaling a broader industry trend, supply chains built for optionality, not for linear EV expansion. China

China Courts Supply Chain Confidence

Tony Hines 19:08

is pivoting in the coming month towards global trade investment and supply chain stability. May was diplomacy heavy with visits from the United States President and the Russian president. It's going to use June to reinforce its role in global supply chain stability through three major platforms the Summer Davos, Qingdao Multinationals Summit, and China International Supply Chain Expo in Beijing. These events aim to reassure global firms of China's commitment to open cooperation, innovation, and predictable industrial policy amid rising global protectionism.

Africa Trade Integration Payment Frictions

Tony Hines 19:51

Africa wants deeper integration and easier intra-African trade. On Africa Day, 2026, there was a call for accelerated integration under the AFCFTA, highlighting the need for a fair and multilateral trading system and improved regional payments infrastructure. A striking insight. Paying Lagos is still harder than paying London, underscoring persistent frictions, capital controls, fragmented banking, foreign exchange shortages that continue to hinder intra-African trade, despite the growing volumes.

Key Bridge Case Reshapes Liability

Tony Hines 20:42

Now do you remember the incident where the Francis Scott Key Bridge went down in 2024? US federal prosecutors have now filed criminal charges against Synergy Marine Group, the Singapore-based manager of the DALLI, the vessel that struck and collapsed the bridge. It's not just civil litigation, it's a criminal case, alleging failures in maintenance, safety management, and operational oversight. It's the first major case where prosecutors are targeting shoreside management, not just the crew. It signals a shift towards criminalizing systemic failure in shipping, holding management companies liable for vessel conditions and crew readiness, expanding the scope of maritime negligence beyond the ship's master. This is the maritime equivalent of the aviation industry's shift after the Boeing seven hundred three seven max crisis. Regulators are no longer accepting complexity as an excuse. The implications, of course, for global shipping are many. Insurance premiums for PI clubs and Hull and machinery will rise. Compliance costs for ship managers will increase. Port stake control inspections will increase. Become more aggressive, and carriers may restructure management contracts to reduce their legal exposure. It's structural change. It's not just the one event of that Francis Scott Key Bridge.

Maritime Disruptions And The New Normal

Tony Hines 22:15

A new data set tracking maritime disruptions show 281 verified blockages or delays across April and May 2026. It's a dramatic increase driven by geopolitical spillovers, pork congestion, and regional instability, and the hotspots are in Sri Lanka where over 2,500 Maldives bound containers are stranded due to political and port handling disruptions. In Latin America, rising logistics costs, as the Middle East instability forces carriers to reshuffle global rotations. And in the Taiwan Strait, there's heightened military activity raising risk levels for Japan bound food and energy shipments. So it's not just single chug points, it's a distributed pattern of medium scale disruption, and it's collectively reshaping those global flows. The system is showing signs of reduced slack, fewer buffers, less resilience, higher volatility, more frequent smaller disruptions, and regional contagion. Instability in one region is rippling through the others. This is the new normal of maritime logistics, many small fires instead of a big blaze. The implications for supply chains, of course, longer lead times for Asia Europe and Asia Africa lanes, higher transshipment risks in Colombo, Singapore and Business, more blank sailings as carriers rebalance rotations, and greater reliance on Cape of Good Hope routing. That's the move around the south of Africa, away from the Suez Canal, even when it's not strictly necessary, because it is about fourteen days longer, and it is about three and a half thousand miles longer, which makes it more fuel expensive and of course time expensive.
